If you have not figured it out yet, I have seen this happen many times in my life with the media:
The economy: Things are really bad and everyone should be scared of losing their jobs, houses, etc. The day a democrat is elected the stories turn to how great the economy is and how revved up the country is with enthusiasm. By the way they report they are trying to influence the coming elections.
The war: We had a bomb that killed 6 iraqi's today, the war is a quagmire, we are losing at every turn. Once a democrat is elected the stories turn to how great we are influencing the reconstuction, no more roadside bomb reporting, we are winning and doing so well that we can start bringing the troops home in a couple of years.
If people would stop listening to the media and judge their individual circumstances on their own we would be a much stronger country
